From the project

ROS driver for the Raspberry Pi based differential drive robot

Base of the robot was made of acrylic glass. The locomotion is provided by 3 wheels, including 1 caster. The two-wheel differential drive based on DC motors makes the machine nonholonomic.

Within the electronic part of the robot's construction, a printed circuit board was designed. All the necessary electronical components including reflective sensors used to measure the distance from obstacles were placed on the board. The sensor providing the largest amount of data is the camera. It is integrated with the Raspberry Pi microcomputer. The extension of the microcomputer's tasks to the reading…
